AUTOMATED TESTING SYSTEM FOR IMPLANTS TO REGULATE INTRAOCULAR PRESSURE

Purpose of work. The implantation of drainage devices in glaucoma is usually performed after previous unsuccessfultreatments and is the patient's last chance to save his vision. The article describes the device that allows automating the process ofpreoperative check-up of implants of different types used for intraocular fluid withdrawal in case of glaucoma. This device will helpto increase the success of the operation and help to preserve the vision of the patients with glaucoma due to the pre-test of theimplants for serviceability and parameters of intraocular fluid withdrawal.Methodology. For the realization of the goal, the authors developed a functional scheme of the automated system formeasuring and controlling the parameters of the intraocular pressure regulation implants based on the microsystem technologyelements.The results. Depending on the material and hardness of the implant, there are three possible cases in which the implantopens earlier and there is a risk of hypotension to the patient's eye, later there is a risk of hypertension and the implant works inthe normal pressure zone. The authors provide testing graphs of three implants of varying levels of hardness, as well as a graph ofthe reproducibility of the characteristics of the non-faulty implant.Scientific innovation. The method of testing implant parameters by way of hardware overpressure creation with thepossibility of automated control parameters of preoperative testing the implants is proposePractical significance. The developed automated system for preoperative testing of implants, which provides:- simplification of the scheme with the simultaneous possibility of automating the process of preoperative testing ofimplants of different types;- allows getting an increase of sensitivity, measurement accuracy, and objectivity of implant parameters determination;- determination of their suitability for use in the medical-surgical practice by the parameters of fluid withdrawal, exactlyopening pressure, closing pressure and reproducibility of the characteristics during the repeated operation, which will contribute tothe efficiency of the performed operations;- reducing the time of implant check, which is limited by 2-3 minutes, and the possibility to save information about theparameters both in electronic (computer) and paper form.
